Description

[Technical field]

[0001] The present invention relates to the technical field of oral irrigators, and in particular to an oral irrigator. [Background technology]

[0002] As people pay more and more attention to oral hygiene, they are also paying more and more attention to oral cleaning. Traditional toothbrushes or electric toothbrushes cannot effectively clean the oral cavity. The principle of cleaning teeth with an oral irrigator is that a water tank carrying an aqueous solution, a motor and a water pump assembly are placed in the shell of the oral irrigator. The water pump assembly is driven by a motor, which sucks the water in the water tank and generates a high-pressure water column, which is then sprayed out through the nozzle to clean the oral cavity.

[0003] The end of the nozzle of an existing oral irrigator is usually fixed on the housing of the oral irrigator and connected to the water outlet of the water pump assembly. In order to allow the nozzle to rotate freely according to the needs of the user, a rotating motor is usually installed at the end of the nozzle to control the rotation of the nozzle.

[0004] However, the cleaning efficiency of the oral cavity by the water flosser is related to the water outlet speed of the high-pressure water column sprayed from the nozzle. When the rotating motor is installed, the end of the nozzle will be elongated in order to set the rotating motor. In addition, if the rotating motor is set directly below the nozzle, the end of the nozzle will also be elongated in order to bypass the rotating motor and connect to the water pump assembly. This will inevitably lead to a decrease in the water outlet speed. Therefore, it is particularly important to design a water flosser that is easy to install, does not reduce the water outlet speed of the nozzle, and can control the nozzle to rotate.

[0060] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0061] In the embodiments provided by the present invention, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined according to A. However, it should also be understood that determining B according to A does not mean determining B only according to A, and B can also be determined according to A and / or other information.

Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification does not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics can be combined in one or more embodiments in any suitable manner. Those skilled in the art should also be aware that the embodiments described in the specification are all optional embodiments, and the actions and modules involved are not necessarily required for the present invention.

[0063] In various embodiments of the present invention, it should be understood that the size of the serial numbers of the above-mentioned processes does not necessarily mean the order of execution.

[0065] As people pay more and more attention to oral hygiene, they are also paying more and more attention to oral cleaning. Traditional toothbrushes or electric toothbrushes cannot effectively clean the oral cavity. The principle of cleaning teeth with an oral irrigator is that a water tank carrying an aqueous solution, a motor and a water pump assembly are placed in the shell of the oral irrigator. The water pump assembly is driven by a motor, which sucks the water in the water tank and generates a high-pressure water column, which is then sprayed out through the nozzle to clean the oral cavity.

[0066] The end of the nozzle of an existing oral irrigator is usually fixed on the housing of the oral irrigator and connected to the water outlet of the water pump assembly. In order to allow the nozzle to rotate freely according to the needs of the user, there are usually the following solutions, such as installing a rotating motor at the end of the nozzle to control the rotation of the nozzle, or setting a bevel gear at the end of the nozzle, which can mesh with the matching teeth on the rotating motor, and the rotating motor drives the bevel gear to rotate to control the rotation of the nozzle.

[0067] However, all of the above methods will bring problems. The cleaning efficiency of the oral cavity by the water flosser is related to the water outlet speed of the high-pressure water column sprayed from the nozzle. When the rotating motor is installed, the end of the nozzle will be elongated in order to set the rotating motor, which will inevitably lead to a decrease in the water outlet speed. In addition, the nozzle is a consumable product that needs to be replaced in time. If a gear is set at the end of the nozzle, it will not only increase the processing difficulty of the nozzle, but also need to consider how to align the bevel gear with the matching teeth on the rotating motor when installing the nozzle, which undoubtedly increases the difficulty of installation. Therefore, it is particularly important to design a water flosser that is easy to install and can control the nozzle to rotate.

[0068] Please combine Figure 1 , Figure 2 and Figure 3aThe dental flosser 10 comprises a housing 1, a rotating assembly 2, a water pump assembly 3, a flushing member 4 and a rotating motor 5; a housing space having a clearance opening 11 is provided in the housing 1, the water pump assembly 3 is accommodated in the housing space, the water pump assembly 3 is arranged along the axial direction of the flushing member 4, and one end of the flushing member 4 passes through the clearance opening 11 and is rotatably connected to the water pump assembly 3;

[0069] A mating surface 40a is provided at one end of the flushing member 4 close to the water pump assembly 3, and the rotating motor 5 is arranged in the accommodating space close to the mating surface 40a. The rotating assembly 2 includes a transmission structure 20 and a fixing member 21, and the fixing member 21 is arranged on the flushing member 4 corresponding to the mating surface 40a. One end of the transmission structure 20 is rotatably connected to the fixing member 21 corresponding to the mating surface 40a, and the other end is rotatably connected to the rotating motor 5.

[0070] The rotating motor 5 drives the fixing member 21 to rotate through the transmission structure 20 , and the flushing member 4 rotates relative to the housing 1 following the fixing member 21 .

[0071] It can be understood that the shell 1 of the water flosser 10 is mainly used to protect the parts placed inside it. The nozzle of the traditional water flosser 10 is usually fixedly connected to the shell 1, so that the punch cannot rotate relative to the shell 1, which causes the user to change the contact angle between the nozzle and the teeth only by bending the arm. In this embodiment, one end of the flushing member 4 passes through the clearance opening 11 and is rotatably connected to the water pump assembly 3. It should be noted that the flushing member 4 is detachably connected to the water pump assembly 3. When the flushing member 4 is connected to the water pump assembly 3, the flushing member 4 can rotate circumferentially around its axis relative to the water pump assembly 3. Specifically, the rotary motor 5 of this embodiment is used as a power source for driving. The rotating assembly 2 is located between the flushing member 4 and the rotating motor 5. The rotating motor 5 first drives the rotating assembly 2 to rotate, and then the rotating assembly 2 drives the flushing member 4 to rotate relative to the water pump assembly 3. The defect that the punch of the traditional water flosser 10 cannot rotate relative to the shell is avoided. The user can easily change the contact angle between the flushing member 4 and the teeth by adopting a conventional brushing posture.

[0072] For details, please refer to Figure 7, the flushing part 4 of the water flosser 10 is usually composed of multiple sections, but its main section 41 is roughly a cylinder, and one end of the cylinder is usually provided with a straight nozzle in the same axial direction as the main section 41, or a curved nozzle in a different axial direction from the main section 41, for water discharge. The other end of the main section 41 is provided with a mounting section 44, and the mounting section 44 is used to connect with the liquid outlet channel 313 provided on the water pump assembly 3. The axial direction of the water flosser 10 in this embodiment refers to the axial direction of the main section 41, and no further elaboration is made here. The flushing effect of the water flosser 10 is mainly related to the water outlet speed of the flushing part 4 and the frequency of driving the internal diaphragm in the internal water pump assembly 3. The space of the housing 1 is limited. If the position of the rotating part 23 and the rotating motor 5 is improperly set, it will usually cause the length of the flushing part to become longer, the water outlet distance to be longer, and the water outlet speed to be reduced. For ease of understanding, the projection direction of the flushing part 4 is defined as the direction of the flushing part 4 along the axis of its main section 41 and the direction close to one side of the housing 1. The projection of the flushing member 4 is the image of its radial cross section projected along the projection direction. If the water pump assembly 3 and the flushing member 4 are not properly positioned. For example, Figure 3b In the embodiment, since the rotary motor 5 is arranged directly below the flushing member 4, the projection of the flushing member 4 does not overlap with the liquid outlet channel 313 on the water pump assembly 3, that is, the flushing member 4 needs to bypass the rotary motor 5 to be connected to the flushing member 4. This undoubtedly prolongs the water outlet distance inside the flushing member 4, thereby slowing down the water outlet speed of the flushing member 4.

[0073] It should be noted that in this embodiment, the water pump assembly 3 is arranged in the projection direction of the flushing member 4, and the rotary motor 5 is arranged close to the flushing member 4, and the rotary motor 5 does not overlap with the projection of the flushing member 4 along the projection direction. The problem of slow water output speed of the water flosser 10 due to unreasonable positioning of the rotary motor 5 and the water pump assembly 3 inside the water flosser 10 is avoided.

[0074] Specifically, in this embodiment, without extending the length of the flushing member 4, a mating surface 40a is firstly provided at one end of the flushing member 4 close to the water pump assembly 3. The rotating member 23 in the rotating assembly 2 is provided on the rotating motor 5, and the rotating motor 5 can drive the rotating member 23 to rotate. The fixing member 21 is provided on the flushing member 4 corresponding to the mating surface 40a, and the transmission structure 20 is a transmission function. When the rotating motor 5 rotates, the transmission structure 20 is firstly driven to move, and the transmission structure 20 further drives the fixing member 21 to drive the flushing member 4 to rotate.

[0075] It should be noted that the mating surface 40a can be a flat surface, or a surface with uneven or curved surfaces, as long as the fixing member 21 can resist the surface of the mating surface 40a when rotating. In this embodiment, the connection between the fixing member 21 and the flushing member 4 can be that the fixing member 21 is integrally formed with the flushing member 4, or can be detachably connected to the flushing member 4, which will not be described in detail here.

[0076] It should be understood that the positions of the rotating motor 5 and the water pump assembly 3 are reasonably arranged in the oral irrigator 10 provided in this embodiment, and the rotation of the rotating motor 5 can drive the rotating assembly 2 to move, thereby driving the oral irrigator 10 to rotate relative to the housing 1. That is, the washing component 4 can be controlled to rotate without reducing the water outlet speed of the washing component 4.

[0077] Furthermore, please combine Figure 3a , Figure 4 , Figure 5 and Figure 6 The water pump assembly 3 includes a bearing shell 31, a containing shell 32, a diaphragm structure 33 and a driving assembly 34 which are detachably connected to the housing 1. A liquid outlet cavity 311 and a mounting cavity 312 are respectively arranged in the bearing shell 31. One end of the liquid outlet cavity 311 is clamped with the containing shell 32, and the other end is connected with a liquid outlet channel 313 provided with a flushing member 4. At least part of the rotating motor 5 is accommodated in the mounting cavity 312. It should be understood that the bearing shell 31 of this embodiment plays the role of connecting with the housing 1 to fix the containing shell 32, and can also form the mounting cavity 312 so that the rotating motor 5 is fixed in the mounting cavity 312. It should be noted that the mounting cavity 312 is arranged close to the liquid outlet cavity 311, so that the size of the housing 1 in its width direction is minimized, and there is a certain distance between the mounting cavity 312 and the liquid outlet cavity 311 to avoid the rotating motor 5 occupying the space of the containing shell 32.

[0078] Specifically, a accommodating chamber 321 and a liquid inlet chamber 322 are formed in the accommodating shell 32. The liquid inlet chamber 322 is provided with a liquid inlet channel 323 connected to the water tank and a connecting channel 324 connected to the liquid outlet chamber 311. The diaphragm structure 33 is arranged between the liquid inlet chamber 322 and the accommodating chamber. A driving component 34 connected to the diaphragm structure 33 is arranged in the accommodating chamber. The driving component 34 is used to drive the diaphragm structure 33 to perform reciprocating motion so that the liquid in the liquid inlet chamber 322 enters into the liquid outlet chamber 311.

[0079] It is understandable that after the containing shell 32 and the bearing shell 31 are snapped together, the liquid outlet chamber 311 is in a closed state, one end of which is connected to the outside world through the liquid outlet channel 313, and the other end is connected to the liquid inlet chamber 322 through the connecting channel 324. It should be understood that a valve can be provided in the connecting channel 324 so that a partition is formed between the liquid inlet chamber 322 and the liquid outlet chamber 311. The liquid inlet chamber 322 can be connected to the water tank through the liquid inlet channel 323. When the driving component 34 is in operation, the diaphragm structure 33 will reciprocate, and when the diaphragm structure 33 reciprocates, it will usually cause the pressure in the liquid inlet chamber 322 to change. When the pressure in the liquid inlet chamber 322 decreases, the water in the water tank will flow into the liquid inlet chamber 322 through the liquid inlet channel 323. When the pressure increases, two situations may occur. One situation is that the diaphragm structure 33 moves to increase the pressure of the liquid inlet chamber 322. At this time, the pressure is sufficient to make the liquid in the liquid inlet chamber 322 spray out through the connecting channel 324, the liquid outlet chamber 311 and the liquid outlet channel 313. Another situation is that the diaphragm structure 33 moves to increase the pressure of the liquid inlet chamber 322. At this time, the pressure is insufficient to make the liquid in the liquid inlet chamber 322 spray out through the connecting channel 324, the liquid outlet chamber 311 and the liquid outlet channel 313. The diaphragm structure 33 will continue to reciprocate, so that the water in the water tank enters the liquid inlet chamber 322, and then the pressure in the liquid inlet chamber 322 gradually decreases. When the pressure in the liquid inlet chamber 322 reaches the critical value, the liquid in the liquid inlet chamber 322 will spray out through the connecting channel 324, the liquid outlet chamber 311 and the liquid outlet channel 313 as soon as the diaphragm structure 33 is squeezed. It should be understood that by setting up the water pump assembly 3, the water in the water tank can be sprayed out through the liquid outlet channel 313, and one end of the flushing component 4 is connected to the liquid outlet channel 313. At this time, after the water is sprayed out, a high-pressure water column can be formed to clean the teeth of the human body, which is simple and convenient.

[0080] Specifically, see Figure 1 and Figure 8 The flushing member 4 is provided with a water outlet channel 45, and the flushing member 4 includes a nozzle section 42, a main body section 41, a clamping section 43 and a mounting section 44 connected in sequence; the mounting section 44 is at least partially accommodated in the liquid outlet channel 313. The surface of the clamping section 43 is provided with a mating surface 40a. For example, Figure 7As shown, the surface of the clamping section 43 includes two opposite mating surfaces 40a and an arc surface 40b connecting the two mating surfaces 40a. It should be understood that after the water is sprayed out from the liquid outlet channel 313, it will first enter the water outlet channel 45 through the installation section 44, and then be sprayed out through the clamping section 43, the main body section 41 and the nozzle section 42 in sequence. In this embodiment, the clamping section 43 of the flushing member 4 will correspond to the fixing member 21, and the mating surface 40a can cooperate with the fixing member 21, so that when the rotating motor 5 drives the rotating assembly 2 to move, the rotating assembly 2 can further drive the flushing member 4 to rotate relative to the housing 1, thereby flexibly controlling the contact angle between the nozzle section 42 and the teeth.

[0081] Specifically, see Figure 7 and Figure 8 , one end of the nozzle section 42 away from the main section 41 forms a nozzle corresponding to the water outlet channel 45, and a cleaning gel or a cleaning solid 46 is arranged in the water outlet channel 45. When the liquid in the liquid outlet cavity 311 enters the water outlet channel 45, the cleaning gel or the cleaning solid 46 is ejected from the nozzle together with the liquid. It should be understood that the flushing part 4 provided in this embodiment can be a flushing part 4 with a cleaning gel or a cleaning solid 46. For example, the cleaning gel or the cleaning solid 46 can be toothpaste. When the flushing part 4 is produced, the cleaning gel or the cleaning solid 46 can be placed inside the hollow channel, so that when the user uses it for the first time, the gums can be cleaned without applying any additional toothpaste. Therefore, the flushing part 4 can also be used as a disposable and replaceable accessory.

[0082] Furthermore, the fixing member 21 can be integrally formed with the mating surface 40a, or the fixing member 21 can be detachably connected to the mating surface 40a. The rotating assembly 2 in this embodiment has various forms, and its specific function is to convert the force provided by the motor into a force to drive the flushing member 4 to rotate relative to the housing.

[0083] In one possible implementation, see Figure 9a For example, the fixing member 21 and the mating surface 40a are integrally formed, and the fixing member 21 is a first toothed structure 24 that protrudes outward or is recessed inward from the mating surface 40a, or the fixing member 21 and the mating surface 40a are detachably connected. A first toothed structure 24 is provided on the side of the fixing member 21 away from the mating surface 40a. The end of the transmission structure 20 close to the fixing member 21 is also provided with a second toothed structure 25 that meshes with the first toothed structure 24. The end of the transmission structure 20 away from the fixing member 21 is rotationally connected to the rotating motor 5. When the rotating motor 5 drives the transmission structure 20 to move, the transmission structure 20 will mesh with the fixing member 21, so that the fixing member 21 rotates along the surface of the transmission structure 20, and then the fixing member 21 and the flushing member 4 rotate relative to the housing 1.

[0084] In one possible implementation, see Figure 9b The transmission structure 20 includes two connecting rods 22 and a rotating member 23. The surface of the clamping section 43 includes two opposite matching surfaces 40a. The fixing members 21 are respectively arranged on the two opposite matching surfaces 40a. The rotating motor 5 extends on one side close to the clearance opening 11 to form a motor shaft 51 with the same axial direction as the flushing member 4. The rotating member 23 is sleeved on the rotating motor 5 and extends in the direction of the two matching surfaces 40a to form a connecting portion 231. A first tooth structure 24 is arranged on the side of the fixing member 21 away from the clamping section 43. The transmission structure 20 is also provided with a second tooth structure 25 meshing with the first tooth structure 24 at one end close to the fixing member 21, and the other end is rotatably connected to the connecting portion 231.

[0085] It should be understood that the rotary motor 5 drives the rotating member 23 to perform reciprocating motion within a preset rotation range, and the preset rotation range is -30° to +30°. It should be noted that under normal conditions, the two connecting rods 22 are parallel to the mating surface 40a, which means that the rotation amplitude of the rotary motor 5 is 0°. When the rotary motor 5 drives the rotating member 23 to rotate, the rotary motor 5 can drive the motor shaft 51 to rotate 30° clockwise or 30° counterclockwise. In this embodiment, when the rotary motor 5 drives the motor shaft 51 to rotate, one connecting rod 22 will move in a direction close to the motor shaft 51, and the other connecting rod 22 will move in a direction close to and away from the motor shaft 51. The connecting rod 22 is meshed with the fixed member 21, and the two connecting rods 22 will apply an opposite force to the fixed member 21, and the two forces act on the fixed member 21, which just drives the fixed member 21 to rotate circumferentially along the axis of the clamping section 43.

[0086] In one possible implementation, see Fig.9c The transmission structure 20 includes a connecting rod 22 and a rotating member 23, two opposite mating surfaces 40a are arranged on the clamping section 43, and the rotating motor 5 extends on one side close to the yield opening 11 to form a motor shaft 51 with the same axial direction as the flushing member 4. The rotating member 23 is sleeved on the rotating motor 5 and extends in the direction of the two mating surfaces 40a to form a connecting portion 231; the fixing member 21 is roughly annular, including a fixing member body 211 and a first connecting column 212 arranged on the fixing member 21, the fixing member body 211 penetrates to form a clamping channel 213, the inner wall of the clamping channel 213 forms a clamping surface 2131 contacting the mating surface 40a, and a second connecting column 232 is arranged on the connecting portion 231. The two connecting rods 22 are respectively arranged on both sides of the fixing member 21 corresponding to the two mating surfaces 40a, one end of the connecting rod 22 is rotatably connected to the first connecting column 212, and the other end is rotatably connected to the second connecting column 232.

[0087] It can be understood that the rotary motor 5 drives the rotating member 23 to perform reciprocating motion within a preset rotation range, and the preset rotation range is -30° to +30°. It should be noted that under normal conditions, the two connecting rods 22 are parallel to the mating surface 40a, which means that the rotation amplitude of the rotary motor 5 is 0°. When the rotary motor 5 drives the rotating member 23 to rotate, the rotary motor 5 can drive the motor shaft 51 to rotate 30° clockwise or 30° counterclockwise.

[0088] Specifically, in this embodiment, when the rotary motor 5 drives the motor shaft 51 to rotate, one connecting rod 22 will move in a direction close to the motor shaft 51, and the other connecting rod 22 will move in a direction close to and away from the motor shaft 51. The two connecting rods 22 will apply an opposite force to the fixing member 21, and the two forces act on the fixing member 21, just driving the fixing member 21 to rotate circumferentially along the axis of the clamping section 43. Specifically, since the matching surface 40a and the inner wall of the clamping channel 213 are adapted, when the fixing member 21 rotates, the inner wall of the clamping channel 213 will abut the matching surface 40a, and generate a force perpendicular to the radial direction of the flushing member 4, so that the flushing member 4 follows the fixing member 21 to rotate circumferentially around the axis of the clamping section 43. At this time, the flushing member 4 will rotate relative to the housing 1. In addition, the flushing member 4 is a consumable product that needs to be replaced in time. If a toothed structure is provided on the flushing member 4, not only the processing difficulty of the flushing member 4 is increased, but also when installing the flushing member 4, it is necessary to consider how the first toothed structure 24 is aligned with the second toothed structure 25 for connection, which undoubtedly increases the difficulty of installation. In this embodiment, the fixing member 21 and the flushing member 4 are detachably connected, so the installation is simple, and the nozzle can be controlled to rotate.

[0089] In one possible implementation, see Figure 9d The fixing member 21 may also not be annular, but may be a protruding structure 214 extending outward from the clamping section 43, or a protruding structure 214 extending outward from the fixing member 21. The fixing member 21 is fixedly connected to the flushing member 4 or is sleeved on the flushing member 4 corresponding to the mating surface 40a. Specifically, the transmission structure 20 includes a rotating member 23, which is sleeved on the rotating motor 5 and extends in the direction of the two mating surfaces 40a to form a connecting portion 231; and one end of the protruding structure 214 away from the fixing member 21 can be connected to the connecting portion 231. When the rotating motor 5 drives the rotating member 23 to rotate in the clockwise direction, a connecting portion 231 will contact the protruding structure 214 and drive the fixing member 21, so that the fixing member 21 and the flushing member 4 rotate relative to the housing 1. When the rotary motor 5 drives the rotating member 23 to rotate counterclockwise, the other connecting portion 231 will contact the protruding structure 214 and drive the fixing member 21 , so that the fixing member 21 and the flushing member 4 rotate relative to the housing 1 .

[0090] It can be understood that the rotary motor 5 drives the rotating member 23 to perform reciprocating motion within a preset rotation range, and the preset rotation range is -30° to +30°. It should be noted that under normal conditions, when the midpoint between the two connecting parts 231 is aligned with the center point of the cross section of the clamping section 43, the rotation amplitude of the rotary motor 5 is 0°. When the rotary motor 5 drives the rotating member 23 to rotate, the rotary motor 5 rotates 30° clockwise or 30° counterclockwise.

[0091] Specifically, please combine Figure 3a , Figure 4 , Fig.10 and Fig.11 A quick release assembly 6 is also provided between the bearing shell 31 and the rotating assembly 2. The quick release assembly 6 includes an elastic member 61 and a quick release member 60. The quick release member 60 includes a quick release piece 62 and a quick release button 63 which are detachably connected to each other. An opening is provided at the shell 1 corresponding to the quick release button 63, and the quick release button 63 is exposed to the shell 1 through the opening. A blocking block 64 is provided at the side of the quick release piece 62 away from the quick release button 63 of the shell 1 or the bearing shell 31, and the elastic member 61 is clamped between the quick release piece 62 and the blocking block 64. A matching groove 441 is provided on the mounting section 44, and the quick release piece 62 corresponds to the matching groove 441 and penetrates to form a limiting channel 620. The elastic member 61 abuts against the quick release piece 62 so that the inner wall surface of the limiting channel 620 matches the matching groove 441.

[0092] It can be understood that although the rotating structure provided in this embodiment can play the role of fixing the flushing part 4. Furthermore, this embodiment provides the addition of a quick-release assembly 6. When the quick-release button 63 is not pressed, the elastic member 61 will always apply a restoring force to the end of the quick-release member 60 away from the quick-release button 63. When installing the flushing part 4, it is only necessary to apply a force to the quick-release button 63. At this time, the quick-release button 63 is forced to push the entire quick-release member 60 to move in a direction away from the quick-release button 63. At this time, the elastic member 61 is gradually squeezed, and when the quick-release button 63 cannot be pressed, the installation section 44 of the flushing part 4 can be passed through the clearance opening 11 and the limiting channel 620 in turn into the liquid outlet channel 313. At this time, the installation of the flushing part 4 is completed. Cancel the application of force to the quick-release button 63. The squeezed elastic member 61 provides a restoring force to push the quick release member 60 to drive the quick release button 63 to rebound, and during the rebound process, the inner wall of the limiting channel 620 close to the elastic member 61 will stop the bottom surface of the matching groove 441, thereby fixing the flushing member 4.

[0093] Further, the limiting channel 620 includes a first limiting channel 621 and a second limiting channel 622 connected to each other, and the inner wall surface of the first limiting channel 621 cooperates with the arc surface 40b. When the flushing member 4 is installed on the water pump assembly 3, and the user does not apply force to the quick release button 63, the restoring force provided by the elastic member 61 will always push the quick release member 60 to stop the bottom surface of the groove of the matching groove 441. It should be understood that the inner diameter of the first limiting channel 621 is smaller than the inner diameter of the second limiting channel 622, and the outer diameter of the mounting section 44 is larger than the inner diameter of the first limiting channel 621 and smaller than the inner diameter of the second limiting channel 622, that is, when the quick release piece 62 stops the flushing member 4, the groove wall of the matching groove 441 will limit the axial direction of the flushing member 4, so that the flushing member 4 cannot be pulled out of the liquid outlet channel 313 under the action of external force. In addition, since the inner wall of the first limiting channel 621 and the inner wall of the matching groove 441 are both the arc surface 40 b , the quick release piece 62 will not limit the flushing component 4 from rotating relative to the housing 1 .

[0094] Specifically, please combine Figure 4 , Fig.10 and Fig.11 The quick release piece 62 is provided with a sliding channel 623 corresponding to the mating surface 40a, and a protruding structure 314 is provided on the side of the bearing housing 31 close to the quick release assembly 6 corresponding to the sliding channel 623. When the quick release assembly 6 moves relative to the clamping section 43, the protruding structure 314 is slidably connected with the sliding channel 623. It should be understood that the cooperation between the sliding channel 623 and the protruding structure 314 can make the quick release piece 62 always move toward the side of the elastic member 61 when the quick release button 63 is pressed, so as to avoid displacement of the quick release piece 62 when subjected to force, resulting in radial deformation of the elastic member 61.

[0095] For further information, see Figure 2 A receiving groove 12 is formed in the receiving space at one end close to the bearing shell 31, and the receiving groove 12 is used to receive different flushing components 4. It should be understood that different types of flushing components 4 can be placed in the receiving groove 12 for users to replace.
